Hi Doc, I am in a relationship with a respectable man but when we first started having sex, everything was fine. However about 2 months in the relationship whenever we have sex I tend to get a very bad rash outside my vagina which burns alot whenever i urinate. This also comes with a heavy discharge which is yellowish green colour and smells aweful. I went to the doctor who test for chamydia and every STDs but everything came back negative. I also got test for hep a, b syhillis and HIV but all came back negative. Eventually when we started having sex again it stopped and I was fine. we did have a 3 week break and we did make love again and it started again. I am at my wits end! I thought it was yeast infection because when we met he was just coming out of a relationship and that lady had diabetes which I know women with diabetes are prone to yeast infection so I am thinking he passed it on to me. I am not sure. In the back of my mind i m thinking if he is cheating on me. Please help. My libia is very red and raw and the discharge is very very heavy. almost immediately after sex i can feel my vagina started feeling different until the next day my vagina get worst. I am also thinking I may be allergic to his semen . Read more: Read message WWW.WWWW.WW Follow us: @ehealthforums on Twitter
